Crank position sensor

Can anyone tell me for sure where the crank position sensor is located. I've heard it may be behind the starter or it may be behind the crank pulley. Just need a verification before I start tearing stuff apart. Also do you have to pull the engine mount to remove the starter?

Here's a diagram, #707, and instructions on the CPS. I'm not sure on the starter, it appears that it should drop out of the bottom but can't confirm.
This looks like it's for the camshaft sensor. Do you have this information for the crankshaft sensor?

Do you have the repair content information for part #713? Not sure what software you have that gives you this information, but it's nice as hell.

Holy crap the scope of this just got a bit bigger. I had no idea I was going to have to pull the catalytic converter off. Jeez

I read it also which seems it's a big project. Again sorry on the crank & cam mix up probably shouldn't be watching the NFL and answer questions.

I just had mine replaced. Probably could have done it myself but too lazy. You pull the balancer off and it's right there. Look on YouTube. I think a guy on there did it without removing anything too. I've never had a car F up and do so many wierd things because of a little sensor.
